vThe present invention relates to an electric operating device for automatic distributors of liquid whose operation is automatically effected when the feed pump of said distributor is itself operated. The device in conformity to the present invention thus relates .to the operation of the said pump.

In conformity to the invention, in the main upright support of the apparatus is mounted a casing of an absolutely leakless nature 0011- I taining an electric motor adapted to drive a speed-reducing device whose driven shaft extends through the said casingthrough a leakless bearing.

When the pump operates by reciprocating motion, on the driven shaft of the speedreducing device is mounted a crank disc to which is pivoted a connecting rod whoseoth r end 1s pivoted to a drlvin g crank d isc loosely mounted on thepump shaft.

The said driving crank v WIlBh tGHODS which are normally n engagement with corresponding recesses in a wheel keyed to the pump shaft.

A nut or like member is provided in order to maintain the disc against the wheel, in such manner that by simply loosening the nut, the disc can be disengaged, and the pump may now be operated by hand if desired.

When the pump is ,ofthe rotary type, two sprocket-wheels carrying a driving chainare keyed respectively to the pump shaft and to the driven shaft of the speed-reducing device. 3 However, the pinion mounted on the shaft of the speed-reducing device is provided with a loose wheel ratchet devicein such manner as to rotate in a certain direction with referintermediate sprocket-wheel carrying two re- .spective drivlng chains whereof one leads from the sprocket-wheel provided with the said loose wheel device and the. other leads to the sprocket-wheel, mounted on the pump shaft. The shaft of this sprocket-wheel'may receive a hand-crank.

The motor drives an air fan adapted to eX- disc is provided intermediate motor casing.

In Fig. 1, 1G is the main upright which supports the distributer and contains the feed pump 11 ofthe distributer whose dehvery pipe 1s shown at 12; at 13 1s a safety by-pass, and at 14 the suction pipe on which is a filter 15.

In the known manner, the shaft'lti of the pump carries'a wheel 17 engaging a like wheel 18 .mounted on the main frame and actuating an eccentric 19. to which is pivoted I in one and the other direction in such man- ,a rod 20 adapted to control the mechanism of the'distributer in any suitable manner.

' The gear Wheel 17 has on its outer face two trapezoidal recesses'61 adapted forthe engagement of two respective tenons 62 oflike form, secured to the disc 29 under the action of a nut 31', (F igs.'2 and 5). In this manner the wheel 17 can be actuated by the disc 29. 'A- centering arm provided in one of the tenons 62' of the disc 29 serves to readily determine, when assembling the device, the

exact position of the corresponding recess v On'the end of the shaft of the electric n10- tor is mounted an air fan 32 rotatable "in an annular chamber 33 situated in the case 50.?

21,- and to the center of the chamber is con- 'n'ec-ted a pipe 34 leading to the exterior of the distributer. A second pipe 35 leads from the exterior of the distributer to any suitable point-of the case21. 1 55.

lows.

The-operation of the apparatus is as fol- VVhen the electricimotor'22 rotates, the

small fan'32 producesa suction in the case 21, and thus-fresh air will enter through the pipe3 5. Thesaid fan also expels air from the case, through the pipe 34. In this'manner,

: the case is not only quite leakless by its construction, but on the other hand the vapors which might enter the said case will be at once expelled by the aerating action of the I shaft.

which is controlled from fan 32. In this manner, no risk is to be apprehended.

In order to avoid all opening of the case 21, while being enabled to lubricate the'rotating parts, each point to be lubricated is provided with a small pipe such as 36, which leads to an externaloiling tube 37 suitably situated.

The rotation of the electric motor 22 effects the rotation, at reduced speed, of the crank 27, so that the connecting rod 28 will be moved, thus causing analternate pivoting motion of the disc 29. As this latter is held fast by the nut 31, on the wheel 17 which i is secured to the pump shaft,- the pump and the distributer will operate in the same conditions as if the pumpwere operated by hand.

In case ofdamage to the electric motor or to the driving parts, the shaft 16 of the pump can be driven by means of a. socket Wrench engaged upon the square end of said However, it is necessary to loosen the nut 3-1 in order to-separatelthe disc 29 from thewheel 17, andthus release thetwo tenons 62 and the arm 30 from therecesses 61 of the wheel17. If this precautienwere not taken, it would be impossible to actupon the pump shaft 16, for as a general rule the speed reducer is non-reversible and :can be glven no other motion than the one it rece ves from the motor.

To again start the motor, the operator turns the gear wheel l7while tightening the nut 31, so that the arm SO, urged by. its spring, Wlll engage in the corresponding recess 61 of the wheel 17, and in this event the tenons 62 are eXactlyin coincidence with the recesses 61, and it i's simply necessary to screw the nut clear down. r I

The motor is supplied by an electric circuit consisting of conductors 38 contained in a leakless tube 39, and leading to a junction box 40, a switch 41 being provided for starting and stopping the motor...

'Figs. 3 and 4 show in detail the ment of the said switch.

It essentially comprises a tilting mercurytube device 42, known per se, which is supplied by the; electric conductors 38 and is adapted to pivot. about an-axle 43, it being secured to an arm 44 carrying a weight 45. The said arm cooperates with'a catch 46 arrangeknob 47.

The arm 44 acts in such manner that the normal position of the rocking device 42 is the one in which the electric circuit is broken- The arm 44- carries a stud or, stop 48 cooperating withlanappendage or arm of a pivoting lever 50 which carries a weight51 and may be'acted upon by a tapered part provided upon a push-button device53. 4).

The form of the lever 50 i'ssuch that when pressing upon the button 53 and thus pivot-' the exterior by a x gaging a hook 55 formed on the end of a rod which is pivoted to a pivoting lever 57 which maybe acted upon at the end of the move ment by a tappet 58 provided upon the distributer dial 59. This dial is of the same kind as is provided upon all automatic distributers, and permits to preliminarily determine the quality of liquid to be delivered by the apparatus.

The operation of the aforesaid device is as follows. 7

When itis desired to start the distributor, the operator turns the dial 559 until the figure corresponding to the quantity of liquid to be supplied appears in an opening 60 of the main support. He then turns the knob 47 so that the rocking device 42will pivot about and will thus bring the stud or stop '48 against the arm 49 of the lever 50. The circuit of the motor is thus closed, and the motor starts in operation. I

When the supply of the liquid is nearly finished, the dial 59 has returned to its original position, and the stud 58 tips up the lever 57 and raises the link 56; the arm 54 is also raised, the lever 50 turns about, and its arm 49 escapes from the stop 48.

The rocking device, which is turned about by its weight 45, resumes its normal position in which the electric circuit is broken.

If it isdesired to stop the electric motor by hand at any time, the operator pushes the button 53, whose tapered part 52 causes the lever 50 to turn in the same conditions as before. i

In the modified construction shown in Figs. 6 and 7, is the main frame or support ofthe distributer supplying the liquid, and

upon the said support is mounted a pump 71 whoseshaft 72 operates ina bearing 73. The suction and discharge conduits of the pump 71 are shown respectively at 74 and7 5; this pump-is of the rotary type, and thus when in operation the shaft 72 must rotate in a given direction. The said shaft carries an eccentric 76 adapted to drivethrough the medium of the rod 20the controlling mechanism of the distributer itself.

On the other hand, the pump 71 is driven the electric motor 22 which is directly 23 to the driving shaft of the Coupled at 24 whose driven shaft is indispeed reducer cated at 25. Y

The parts are mounted in such manner that the shaft 25 of the speed reducer is parallel with the shaft 72 of the pump 71.

To the shaft 72 of thepump 71 is keyed a sprocket wheel 77 actuated by a chain 78 engaged with one set of teeth of the double sprocket wheel 79. The other set of teeth of this double wheel engaged a second chain 80 through the medium of a loose wheel device (Fig.7.)m: f

The double wheel 79 ismounte'don ashaft 82 supported by-the main frame'70 of the co-operating with sprocket wheel si quni- 2 ed onftheshaftf25 of the speed-reducefr'24 apparatus;one'end 84 of the shaft 82 extends to the outside ofthe said frame, it being protected by aremovable cap83. Thisend '84.

of the shaft 82 has a square or like form,

adapted for engagement with an operating ian dle, not shown.

The operation of the modified apparatus I shown in Figs. 6 and 7 is as follows.

During the normal functioning of the apparatus, with the motor in operation,.the 7 motor drives the shaft 25 {at reduced speed,

and also drives the double sprocket Wheel 79 by means of the chain 80; saidwheel drives the sprocket wheel 77 andalso the shaft- '7 2 of the pump 71 by means of the chain 78, and

thus. the pump will .be operated, and the .mechanism of the distributer will be driven by the rod 20. V I i If the motor 22' or the speed-reducer24 are put out of use by accident, and if it is still desired to make use of the distributer, the operator removes the cap 83 and mounts .a handle upon the end 84 of the shaft 82. This shaft, and hence the sprocket wheel 79,

are thus driven'in the proper direction, and this will also rotate the shaft 72 of the pump 71, as before.

On the other hand, this rotation is not hindered by the presence of the speed-reducer 24, which is usually non-reversible, as the lower sprocket wheel 81 will rotate with reference to the shaft 25 of the said speed-reducer, due to the ratchet wheel 85.

It is thus observed that in order to change arrangement of the loose 5 Y over from motor operating to handv operating, it is not necessary to remove any of the parts, nor to perform any additional operations.

In the manufacture of the apparatus, care has been taken to use diameters for the' sprocket wheels 77 and 79 such that the-pump shaft will be driven at the most suitable speed, both for the motor drive and for the operating .by the handle. As a general rule, the ratio between the speed of the pumpshaft and the speed of mately 113. p
